...does this explain why my bluetooth mouse or trackpad becomes unresponsive on my 2012 MacBook Air?

I haven't noticed a correlation with USB disk access and the mouse going limp, but now i'll be looking out for it.

Apple actually has a support article on the topic[0].

The study says the interference is there if the disk is being accessed or not. Wrapping it in tinfoil seemed to make a difference though.
